Electric power steering system

Abstract

An electric power steering system includes: a housing defining a receiving space therein; a worm shaft disposed in the receiving space to be engaged with a worm wheel; a tilt plug coupled to an inner surface of the housing to be fastened to a predetermined position, and coupled to the worm shaft which is inserted into the receiving space to support the worm shaft; and an elastic supporter which is installed to the housing to elastically support the tilt plug toward the worm wheel. The tilt plug is provided with a coupling protrusion which is protruded from an end portion of the tilt plug in a center axis of the tilt plug and slides into an inner surface of the housing, and the inner surface of the housing is provided with a coupling indentation into which the coupling protrusion slides to restrict rotation of the tilt plug.
